PATENTEI] JUN28 IHYI INVENTUR CARBURETOR AIR INTAKE FILTERS Thisinvention relates to air filters. An annular pleated filter with aauto-pollution warning device in combination with a filter paper couplercoupling the lose ends of the pleated filter paper completing a circlewhich is bonded to the top and bottom gaskets.

Our majorproblem all over the country today is auto air pollution andwhat is being done about reducing it. Automobile owners, gas stationsand auto repair shops do not have a way to determine the condition ofauto carburetor air intake filters, a major cause of auto air pollution.The only means they have to determine the condition of auto air intakefilters is compressed air hose and a drop light. But this is not the wayto determine the condition of a carburetor air intake filter if it is upto manufacturers specification or if it is in need of replacement. Inthe meantime automobiles are burning excessive gas, excessive oil, lossof power, car engine stalling which causes many accidents on the road.Unnecessary wear on the engine, improper mixture of air and fuel are amajor causes of carburetor fires, and excessive smoke from the exhaustsystem. All put together we have auto air pollution.

It is therefore an object of this invention to improve carburetor airintake filters with a combination vacuum-sensing sound-producing warningreed coupler which is in combination with a filter paper coupler,coupling the lose ends of the pleated filter paper. The device is towarn the operator of a motor vehicle which is being operated that it ispolluting the air due to a faulty carburetor air filter which needsimmediate replacing. The warning sound from the combinationvacuumsensing sound-producing warning reed coupler will only sound whenthe carburetor air intake drops below auto manufacturers specifications.With the running of the engine the waming sound will indicate thecarburetor air intake air filter is faulty. The warning device willcontinue to sound until the carburetor air intake filter is replacedwith a new one to help reduce auto air pollution.

These prominent objects are accomplished by the novel construction andarrangement of parts hereinafter described and shown in the accompanyingdrawing, constituting an essential component of this disclosure, and inwhich:

FIG. 1 illustrates my new invention an improved carburetor air filter incombination with an antipollution warning device which is a combinationwarning post and filter paper lose end coupler. In the warning postcoupler there is a aperture supported within the aperture there is acalibrated vacuumsensing sound-producing button warning reed and dustcover which are presed into the aperture. When the air filter becomesclogged it will then suck air through the aperture in the device causingthe calibrated sensing reed to vibrate producing a warning sound toindicate a clogged air filter. On each side of the combination warningpost filter paper coupler there are flexible self-clamping jaws. Thelose ends of the filter paper are inserted into the jaws completing acircle which is then bonded to the top and bottom end gaskets, I

FIG. 2 shows the combination warning post and filter paper coupler withwarning reed pressed into the aperture,

FIG. 3 shows the auto pollution warning reed a combinationvacuum-sensing sound-producing button reed.

Referring in greater detail to the drawings the new invention will beseen to consist of a carburetor air intake filter 15, with a auto airpollution warning device 16 which is a combination warning post andfiltering paper 20 lose end coupler 16. in the warning coupler 16 thereis a aperture 17 therethrough supported within the aperture 17 there isa calibrated vacuumsensing sound-producing button warning reed 18 whichis pressed into the aperture 17. When the air filter 15 FIG. 1 becomesclogged it will then suck air through the aperture 17 in the device 16causing the calibrated button reed 18 to vibrate producing a warningsound to indicate a clogged air filter 15 FIG. 1. On each of thecombination warning post coupler 16 there are flexible self-clampingjaws 19 into the jaws 19 the lose ends of the pleated filtering paper 20are inserted into the jaws l9 clamping the lose ends of the pleatedfiltering paper 2030 each side of the device 16 completing a filter l5circle which IS then bonded to the top and bottom end gaskets 21 asshown in FIG. 1 cutaway view.

It is to be understood that the device and warning reed will vary insize and design to accommodate due to difierent sizes and designs of airfilters.

With the invention installed and in operation in its factory specifiedcarburetor base and housing it will maintain carburetor air intake tomanufacturers specifications and will help reduce auto air pollution.

From the foregoing it will be seen that a novel unusually practicaldevice for the purpose has been shown and described in its best knownembodiments; therefore that is claimed as new and sought to secure byLetters Patent, is:

lclaim:

1. An air intake annular pleated filter in combination with anantipollution-warning device comprising a warning post coupler having anaperture therethrough, a calibrated vibrating sensing reed and dustcover supported within the aperture whereby the suction of air throughthe aperture vibrates the calibrated sensing reed producing a warningsound to indicate a clogged air filter, each side of the warning postcoupler having a pair of flexible self-clamping jaws, the lose ends ofthe pleated filtering paper being positioned between the flexible jaws,whereby the lose ends of the filter paper are clamped and secured inposition a dusttight coupling, the completed filtering paper circle withthe device being bonded to the top and bottom end gaskets of filter.
